Hi
I’ve created a python method for making a jet colour map which clearly shows small changes around a given point in the colour map, (i.e. the opposite of a diverging colour map http://www.sandia.gov/~kmorel/documents/ColorMaps/ ).
This looks something like figure four on: http://biomedicaloptics.spiedigitallibrary.org/article.aspx?articleid=1828750
If this is something that is interesting for implementation in matplotlib, I would be happy to clean up my code and submit a patch with it?
Kind regards
Pål
Pål,
Matplotlib already has a jet colormap and has moved away from using it as the default for the very reasons listed in the first paper you site. How is your jet colormap different? Can you provide a comparison with the existing colormap? Does it overcome the drawbacks listed in the Sandia Nat’l Labs paper?

Hi Paul
I’m aware that matplotlib has moved away from the jet map, which in most cases I would agree is a good thing.
My map is not a replacement for the jet colourmap, or any other colourmap.
My map is the “inverse” of the diverging colourmaps, seeking to enhance small changes around a certain part of the colourmap (normally the centre, but it can be set by the user).
In order to show the difference I have generated four test plots. Since I don’t want to fill your inbox with attachments, they can be found at http://sudodolphin.blogspot.no/2014/03/creating-colourmaps-enhancing-small.html
with a description.
Cheers
Pål
